-A TTORNE Y Patented Mar. 1, 1932 UNETEE") TATES ALBERT NIEMAN, OFFRANKLIN, OHIO SNOW SCRAPER Application filed August 15, 1930.' SerialNo. 475,513.

My invention relates to a snow scraper.

It is the object of my invention to provide a snow scraper that isadjustable as to the angularity of the scraping blade with respect tothe handle so that the conditions of the snow may be met by a properadjust ment of the mechanism.

It is a further object to provide a novel means of very cheaplyproviding such an adj ustment while at the same time securing therequisite strength.

It is a still further object to provide a system of bracing incombination with the adjusting means.

Referring to the drawings:

Figure 1 is a top plan view of the scraper;

Figure 2 is an inside elevation thereof;

Figure 3 is a bottom plan view thereof;

Figure 4 is a section on the line 44: of Figure 1.

Referring to the drawings in detail, 1 is a vertical scraper platehaving struck-up ribs 2 arranged about the margin of the plate.

011 the inside face of the plate is mounted an arcuate adjusting bracketcomprising a vertical face plate 3 attached by the bolts 1 to thescraper 1.

From this face plate extends an arcuate member 5 having a slot 6 forreceiving a clamping bolt 7 that is clamped by the wing nut 8.

The upper face of the portions 9 and 10 of the arcuate plate 5 on eitherside of the slot 6 are provided with V-shaped grooves 11 aligned withone another for receiving a wedge shaped shoulder 12 adjacent each sideof the clamping plate 13, which carries the bolt 7. This clamping plate13 rests upon the members 9 and 10 of the arcuate plate 5 while the head14 of the bolt 7 engages the underside of the arcuate members 9 and 10.The clamping plate 13 is provided on one end with a finger 15 which ispivoted at 16 to an eye 17 on the face plate 3.

The other end of the clamping plate 13 is formed into a thimble 17 a forreceiving the scraper handle 18.

The angular relationship between the plate 1 and the arcuate adjustingplate 5 is maintained and the strains thereon are absorbed by thediagonal braces that extend downwardly and outwardly from the plate 5 tothe scraper -1 as at 19. These braces are attached at 20 to the plate 1and at 21 to the plate 5.

It will be understood that I desire to comprehend within my inventionsuch modifications as may be clearly embraced Within the scope of myclaims and invention. I

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. In combination, a scraper plate, a face plate attached to the scraperplate and having thereon an angularly disposed slotted arcuate adjustingplate, braces between said adjusting plate and scraper plate and ahandle pivotally mounted on the face plate and adjustably clampedthrough the slot to the adjusting plate.

2. In combination, vertically disposed scraper plate having struckupreenforcing ribs thereon, a face plate attached to the top thereof, anarcuate adjusting plate integral with said face plate, braces betweenthe bot- F tom of the scraper plate and the adjusting plate, a handle,means pivotally supporting the handle on the face plate, and meansadjustably connecting the handle and adjusting plate.

3. In combination, vertically disposed scraper plate, a face plateattached to the top thereof, an arcuate adjusting plate integral withsaid face plate, a handle, means pivotally supporting the handle on theface plate, means adj ustably connecting the handle supporting means andadjusting plate and diagonal brace means extending from the adjustingplate to the corners of the scraper plate.

4. In combination, a vertical scraper plate, an arcuate slottedadjusting plate on said scraper having an upper face transversed by aplurality of depressions, a plate having a finger pivoted on saidadjusting plate adjacent the scraper plate, spaced rib members on theunderside of said plate adapted to engage in said transverse depressionsin the adjusting plate, a clamping means extending through and beneathsaid slot in the adjusting plate for adjusting the position of saidhandle support with respect to said scraper plate and a handle thimbleon said plate.

5. In combination, a vertical scraper plate, an arcuate adjusting plateon said scraper having a slotted upper face transversed by a pluralityof depressions, a plate having a finger pivoted on said adjusting plateadjacent the scraper plate, spaced rib members on the underside of saidplate adapted to engage in said transverse depressions in the adjustingplate, a clamp means extending through and beneath said adjusting platefor adjusting the postion of said handle support With respect to saidscraper plate and diagonal braces between said scraper plate and saidadjusting plate.

In testimony whereof, I afliX my signature.

ALBERT NIEMAN.
